This professional weather centre consists of a base station, thermo-hygro sensor, wind sensor and rain sensor and fixings. The received data is continuously updated to bring you the latest weather information on the base station''s large LCD screen. The outdoor thermo-hygro sensors is the main data communication unit since both the wind and rain sensors are connected to the thermo-hygro sensor for operating power and rely on it to communicate to the base station. Weather data sent from the thermo-hygro sensor is transmitted through a wireless link.
